Struggling with mesh morphing in secondlife

In conclusion, we can NOT implement custom mesh morphing in secondlife up to date. Still morph target is community proposal level.

However some adventures are trying to implement mesh morphing in secondlife. Actually it’s NOT vertex morphing but until Lindeln lab implement custom vertex morphing, it might be only one way we can do it in-world.

Especially facial expression is so hard to implement without morphing.
In order to make something happen without vertex morphing in secondlife, we can use “flick book”.

Blender 2.65a provides us “collada exporting with shapekey” option. Using this option, we can make transformed mesh object by shapekey.

Uploading these meshes, we can see mesh like “linked prims”. By LSL llSetLinkAlpha and so on, we can control transparency of each mesh. It means we can make flick book animation as follows.

But there are some issues we should improve. The way is still long and long .
